Battery ChargersBattery management products are total power management ICs (TPMICs) that manage the charging, sequencing, and protection of lithium-ion/polymer batteries in personal portable electronics. Skyworks’ linear and switching chargers are designed for single and/or dual cell lithium-ion/polymer batteries. These full-featured battery management ICs maximize charging speed and minimize power loss during power delivery to the system. Additionally, they offer integrated system protection using USB and/or adaptor input and dynamic charging capabilities. Many of these products contain unique circuit features to provide advanced IC thermal management during charging and proprietary input power control when supplied from USB port sources. New additions to this product line also feature over voltage protection up to 28 V.

Linear Chargers Skyworks’ linear chargers are designed for single and dual cell lithium-ion/polymer batteries and offer an attractive, low-cost, low noise solution. These full-featured battery management ICs provide multiple levels of power savings, with system protection integrated inside along with single path, dual path, and dynamic charging capabilities. Electrical specifications are shown in Table 1.

Switching Chargers Linear charger ICs commonly used today to charge single-cell lithium-ion batteries offer an attractive, low-cost, low noise solution, but they can’t deliver the higher efficiency levels needed to support higher charge rates and shorter charging cycles. Switching chargers, on the other hand, offer dramatically improved efficiency and higher charge rates. By using the best of both charging methodologies, Skyworks’ switching chargers offer portable system designers a new way to quickly charge a new generation of higher capacity batteries while minimizing the inherent noise of switch-mode power supplies. Electrical specifications are shown in Table 2.

Supercap ChargersSkyworks supercap chargers are programmed, current limited P-channel metal-oxide-semiconductor field-effect transistor (MOSFET) power switches designed for high-side load-switching applications, such as solid-state drive (SSD) memory buffer saving. With programmed current limits, these devices ensure that the power ratings of the host are not exceeded, balancing the system load and supercap charging current automatically to provide enough system load current in top-priority. The integrated discharge path control assures that the system load can still be supported in the short term when the input power has not fully charged the supercap. The current limit is programmed by an external resistor allowing ±10% accuracy at room temperature. Electrical specifications are shown in Table 3.

DC/DC Converters (Switching Regulators)Skyworks’ high efficiency pulse width modulation (PWM) switch-mode voltage regulators are ideal for a wide variety of products such as smartphones, PNDs, notebook computers, set-top boxes, digital still cameras, and other portable electronic devices. Solutions are available for a wide range of output power, optimizing both size and performance for specific power levels. The switch-mode products utilize high switching frequencies to minimize output inductor and capacitor size. Internal compensation eliminates additional external components. These products provide excellent light load efficiency and minimum light load ripple. In addition to excellent efficiency, many SwitchReg™ products offer fast turn-on time and fast transient response capabilities. Taking advantage of advanced modular bipolar CMOS DMOS (BCD) processes allows very low resistance switches and eliminates the need for special packages that require additional thermal relief.

Step-up Converters Step-up converter solutions are available for a wide range of output power, optimizing both size and performance for specific power levels. The switch-mode products utilize high switching frequencies to minimize output inductor and capacitor size. These devices are available in fixed and adjustable outputs and are designed to be stable with both ceramic and titanium output capacitors. Other standard features include over-current, over-temperature, on/off enable, and power good indicator circuits. Electrical specifications are shown in Table 4.

Step-down Converters Step-down converter solutions are available for a wide range of output power, optimizing both size and performance for specific power levels. The switch-mode products utilize high switching frequencies to minimize output inductor and capacitor size. These devices are available in fixed and adjustable outputs and are designed to be stable with both ceramic and titanium output capacitors. Other standard features include over-current, over-temperature, on/off enable, and power good indicator circuits. Electrical specifications are shown in Table 5.

Low Drop-out (LDO) Linear Regulators Linear voltage regulators (PowerLinear™) products include MicroPower™, NanoPower™, and OmniPower™ LDO linear regulators which provide regulated power sources in products such as smartphones, PNDs, notebook computers, set-top boxes, digital still cameras, and other portable personal electronic devices. Skyworks’ LDO regulator products are designed to provide a well regulated power supply while at the same time maximize the performance for a given application. NanoPower™ LDO regulators typically operate with a ground current level of 1.1 µA. The MicroPower™ product line has LDO regulators optimized for low output noise and high power supply ripple rejection, making them well suited for sensitive RF and wireless circuit applications. Other MicroPower™ single- and dual-channel LDO regulators from Skyworks feature fast transient response to meet the most demanding load requirements. OmniPower™ LDO regulators are suitable for general purpose linear regulation requirements across a wide range of applications. All Skyworks LDO regulators are designed to be highly reliable and stable over a wide range of operating conditions.

In addition, LDO regulator devices function with a wide variety of input and output capacitor types. However, they are ideally suited for stability with ceramic capacitors. Low-cost ceramic capacitors are recommended to help increase circuit performance, reduce printed circuit board area, and minimize cost. To further enhance application reliability under adverse operating conditions, all PowerLinear™ LDO regulators include over-current and over-temperature protection circuits. Electrical specifications are shown in Table 6.

Display and LightingLighting Management Units Given the complexity and diversity of feature sets found in today’s smartphones, designers can gain tremendous advantage in terms of design time and cost by using Skyworks’s lighting management unit (LMU) solutions. These devices drive multiple LEDs as well as integrate multiple LDOs linear regulators. Optimized for single-cell lithium-ion/polymer powered systems, the unique capabilities of these devices make them ideal for I2C-based high performance smartphones and other mobile devices. LMUs also add an automatic fade-in/fade-out backlight control that simplifies design and reduces processor overhead. Electrical specifications are shown in Table 7.

RGB LED Controllers These SmartSwitch™ devices are members of the Application Specific Power MOSFET™ (ASPM™) product family. They are intended for controlling RGB fashion lighting in portable products and operate with an input voltage ranging from 1.8 V to 5.5 V, making them ideal for 2.5 V, 3.3 V, or 5 V systems. They can also be used for a combination of general purposes where a load requires a low-side switch connection to ground.

These devices simplify design and layout limitations by eliminating the need for multiple general-purpose input/output (GPIO) control lines and discrete MOSFETs to control product features. To simplify switch implementation and reduce pin count, the state of each output channel is controlled with a single GPIO via the EN/SET pin using Simple Serial Control™ (S2Cwire™) one-wire interface. Electrical specifications are shown in Table 8.

White LED DriversSkyworks offers a wide array of innovative solutions for white LED backlighting including regulated voltage output charge pumps and regulated current output charge pumps. Regulated voltage charge pumps are ideal for use in low-cost LCD panel backlighting applications. Regulated current charge pumps provide constant current source or sink outputs to drive white LEDs. By providing constant current to a white LED, uniform brightness can be assured across an array of white LEDs regardless of variations in the LED forward voltage. Products in this device family use single and multiple fractional charge pump topologies to maximize voltage conversion efficiency from lithium-ion/polymer batter sources. Electrical specifications are shown in Table 9.

Multi-function Power Management Integrated Circuit (PMIC/PMU) These devices are highly integrated system power management units offering a wide combination of step-up charge pump regulators, step-up and step down switching regulators, and low drop out regulators. Electrical specifications are shown in Table 10.

Power Half Bridges Skyworks’ power half bridges include multiMHz power switches that can be used to provide compact voltage regulation in high-speed power supplies. Integrating input level shifting, high-speed break-before-make (shoot-through protection) circuitry, and low resistance, these power MOSFETs reduce board space, parts count, and stray parasitics in switching power supplies. FastSwitch™ buffered half bridge products may be used to drive inductors directly, as high-current gate drivers for discrete power MOSFETs. In addition, a dual buffered half-bridge may be used to drive multiple outputs or can be configured as a full bridge to affect a DC motor or Class-D audio driver. Electrical specifications are shown in Table 11.

Port Protection and Power DistributionCurrent Limited Load Switches (USB PCMCIA)Current Limited Load Switches are designed for high-side power switching applications to cover a wide range of port protection applications for USB, PCMCIA (PC cards), and IEEE 1394 (FireWire) ports in desktop and notebook computers. Port protection switches provide inrush current limiting, short-circuit and over-temperature protection, input control level shifting, and fault flags. Designers can select different current limit options from preset thresholds to user-adjustable limits using just one external resistor. Single, dual, and quad switches are available to fulfill a wide array of application requirements. Devices intended for USB applications have complete Underwriters Laboratories® approval.

Single Input High Side Switches / Current Limiters

These SmartSwitch™ devices are members of the Application Specific Power MOSFET™ (ASPM™) product family. The devices are available in a number of channel configurations and have an integrated current-limiting circuit to protect the input supply against large changes in load current which could cause the supply to fall out of regulation. Electrical specifications are shown in Table 12.

I/O Expander Serial Controlled Load Switches These SmartSwitch™ devices are members of Skyworks’ Application Specific Power MOSFET™ (ASPM™) product family. They are targeted for I/O expansion applications and operate with an input voltage ranging from 1.8 V to 5.5 V, making them ideal for 2.5 V, 3.3 V, or 5 V systems, as well as systems powered by lithium-ion batteries. These devices can also be used for general purpose power load switching.

To simplify switch implementation and reduce pin count, the state of each output channel is controlled with a single GPIO via the EN/SET pin using Skyworks’ Simple Serial Control™ (S²Cwire™) one-wire interface. These devices have very low quiescent supply current significantly improving power efficiency. Electrical specifications are shown in Table 13.

W W W. S K Y W O R K S I N C . C O M 5

Over Voltage ProtectionSkyworks’ over-voltage protection (OVP) switches provide up to 28 V over-voltage and overcurrent protection when powering low-voltage systems such as cell phones, MP3, and PDAs or when charging Lithium Ion batteries from a badly regulated supply.

These devices are inserted between the power supply or charger source and the load to be protected. The devices consist of a low resistance OVP switch, under-voltage lockout protection, over-voltage monitor and protection, over-current protection, battery over-voltage protection, fast shut-down circuitry, and a fault output flag. In normal operation the OVP switch acts as a slew-rate controlled load switch, connecting and disconnecting the power supply from IN to OUT. A low resistance N channel MOSFET is used to minimize the voltage drop between the voltage source and the load and to reduce the power dissipation.

When the voltage on the input exceeds the programmed over-voltage trip point, the device immediately turns off the internal OVP switch disconnecting the load from the abnormal voltage, preventing damage to any downstream components. In the case of an over-current condition, it limits the system current at the threshold value, and if the over current persists, the OVP switch is turned off after a blanking period. If the battery voltage rises to an unsafe level battery over-voltage protection (BOVP) threshold, the IC disconnects OUT from the charging input power IN until the battery voltage returns to an acceptable value. BOVP or over-current protection (OCP) blanking time ignores short-time transients of over-battery voltage and overload current. Additionally, these devices also monitor their own die temperature and turn the OVP switch off if it becomes too hot. Electrical specifications are shown in Table 14.

Slew Rate Controlled These SmartSwitch™ devices are members of the Application Specific Power MOSFET™ (ASPM™) product family. They are intended for high-side load-switching applications and operate with an input voltage ranging from 1.8 V to 5.5 V, making them ideal for 2.5 V, 3.3 V, or 5 V systems. These devices have low RDS(ON), allowing a low forward voltage drop and high current handling capability. Electrical specifications are shown in Table 15.

Supervisors/Monitors, Voltage Detectors – MicroprocessorsThe microprocessor supervisor product line offers significant enhancements to Skyworks’ standard voltage detectors. These devices provide a variety of additional user-selectable options beyond simple power-on or low-voltage reset functions. Selectable enhanced features may include reset delay functions, manual reset capabilities, and watchdog timers. Microprocessor supervisor devices are commonly used in notebook computers, cellular telephones, portable electronic products, and embedded systems. Electrical specifications are shown in Table 16.
